I am using IMX6Q saberlite board and using linux-2.6.38 on it. I am having an issue in using its watchdog. The problem is this that it seems that there is no way to stop or disable watchdog once its activated. I have kept the nowayout parameter of driver(imx2_wdt) to 0. In the driver if a magic close is performed driver keeps on pinging watchdog in order to avoid a reboot. Now if a shutdown is performed the system restarts after 128 seconds. Is there any way to properly shutdown the system without a reboot due to watchdog.
